摘要: Methods of producing gold-palladium catalysts suitable for use in the production of vinyl acetate may include drying the catalyst after the incorporation of a promoter at higher temperatures (e.g., 160°C or greater) to restructure the metals and/or alloys on the catalyst. The restructured catalyst advantageously has increased catalytic activity and improved stability.

摘要: Processes for aromatizing hydrocarbons include contacting the hydrocarbons with a catalyst composition comprising a metal oxide dispersed on a surface of a zeolite support, where contacting the hydrocarbons with the catalyst composition causes at least a portion of the hydrocarbons to undergo a chemical reaction to form aromatic hydrocarbons. The catalyst composition is prepared by a synthesis process that includes combining the zeolite support with a hydrocarbon solvent to form a zeolite mixture, where the hydrocarbon solvent pre-wets the pores of the zeolite support. The synthesis process further includes combining a polar solvent comprising a metal salt with the zeolite mixture to form an impregnated zeolite support. The synthesis process also includes drying the impregnated zeolite support and calcining the impregnated zeolite support to convert the metal salt to the metal oxide, thereby forming the catalyst composition.
